What happens when an engineer builds a smart garden? This Arduino-powered system automates watering while collecting ...

If your home has old lead water pipes, there's a chance that harmful concentrations of lead may be present in your water. An experimental new device could soon allow homeowners to check for ...

The E-Tongue works by applying a voltage to a water sample, causing any lead ions present to stick to the sensor’s gold electrode. Then, the voltage is reversed, causing the lead to come off the ...

Director of Water Supplies Roger Wong on Thursday said sensors will be installed by 2027 to monitor the change of water pressure in water mains. Wong was speaking on an RTHK radio programme after ...

These low-cost water level sensors are made of a small solar panel, batteries and an alarm. When water levels start to rise, city officials will be alerted by the ping. "So the fire chief will get ...

In this paper, first, based on a well-designed double-layer distributed-sector conductance (DLDSC) sensor, systematic oil-water and gas-liquid two-phase flow experiments are carried out to capture ...

Optical flow sensor is able to detect UAV’s motion with respect to the ground, and thus, it can be incorporated in the integrated navigation system to enhance the positioning accuracy. However, the ...

The final, formatted version of the article will be published soon. Water Distribution Systems (WDS) are critical infrastructure assets that deliver water from source to consumers. The increasing ...
